Abstract
A high-pass bird cage coil serves as the whole-body RF coil in an NMR system. This coil is detuned when other RF coils are used to transmit or receive during a pulse sequence. This detuning is accomplished by detuning circuits that contain pin diodes which shunt the tuning capacitors in the bird cage coil.
